Table 2. List of presently recognized taxonomic names erected for British dinosaur (and 
possible dinosaur) taxa, though without misspellings. Where the genus-level classification of a species remains uncertain we have usually retained the generic name used earliest, even though that allocation is usually incorrect. Subjective junior synonyms are included as separate entries as, though often assumed to be synonymous with better known taxa, it is often not possible to establish this beyond question. Such taxa are here regarded as nomina dubia. Abbreviations: sjs = subjective junior synonym; sss = subjective senior synonym; ojs = objective junior synonym.
